Recent findings presented at the OB European Society of Human Reproduction and Embryology reveal a significant correlation between microplastics in human testicular tissue and decreased sperm counts. Analyzing 1,200 men across 15 studies (2010–2024), researchers found microplastics in 68% of testicular samples, particularly polyethylene and polystyrene, associated with inflammation and oxidative stress. This alarming link suggests that environmental exposure could contribute to male infertility, necessitating further studies to establish clearer causal relationships and explore underlying mechanisms.
